"It would be hard to imagine a better guide to this difficult subject." -- Scientific American In Three Roads to Quantum Gravity, Lee Smolin provides an accessi

Quantum theory and Einstein's theory of relativity are at the centre of modern theoretical physics, yet, the consistent unification of both theories is still el

Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the tw

Containing contributions from leading researchers in this field, this book provides a complete overview of this field from the frontiers of theoretical physics

Leading theorists share their important insights into the ongoing quest of theoretical physics to find a quantum theory of gravity.
